Symbol of Promise Episode 8

The battle they just had at Grand Tower cast a shadow on Mirai and the others in many ways. Saki, who wasn't able to participate in the fight, seems to be bothered by something. She then asks Mirai to kill her. Why was the kind and ordinary girl Saki chosen to be a God Candidate? Mirai finds out the truth and then asks Saki to make a certain choice. Meanwhile, high school student Kanade Uryu, who was actually Metropoliman, seems to be plotting his next move as well.
